Note:The following steps mentioned below are followed on a Windows Vista and Windows 7 operating system and they might differ with different operating systems.

If the above steps do not resolve the issue then Try performing SFC scan on the computer.

SFC /scannow is a super-useful command you can use in any Windows version. When the SFC (System File Checker) command is used with the /scannow switch, the tool will scan all of the important Windows files on your computer and replace them as necessary.

Missing and corrupt operating system files (like many DLL files) are arguably the biggest cause of major Windows issues. Considering that, plus the fact that SFC /scannow is completely automatic and very easy to use, the tool should usually be one of your first troubleshooting steps.
